In order to take into account the settings for the start and end of when commercials are played, you must update the advertising playlists and events from time to time. This can (and should) be done automatically. To do this, click "Create playlists and events", and enable the option "Create event to automatically update ads" in the new window. Choose an update period - every hour or once a day. If you need to run and shoot ads every hour on the nose, they must be updated once an hour.
